Hello EveryOne,

I was trying to get all Associated Enitity with below code but receiving error. 

CrmServiceClient Con = CrmHelper.CrmConnection(textBox6.Text, textBox7.Text, textBox2.Text, textBox3.Text);
             RetrieveEntityRequest retrieveBankAccountEntityRequest = new RetrieveEntityRequest
            {
                EntityFilters = EntityFilters.Relationships,
                LogicalName = textBox5.Text
            };
            RetrieveEntityResponse retrieveBankAccountEntityResponse = (RetrieveEntityResponse)Con.Execute(retrieveBankAccountEn

An unhandled exception of type 'System.NullReferenceException' occurred in Microsoft.Xrm.Tooling.Connector.dll

Additional information: Object reference not set to an instance of an object.

    Hello Everyone,

    Problem solved.

    It was the issue with connection string. i have setup my CRM with HTTPS and due to that organization services were deployed on HTTPS. i changed the setup and CRM is running on HTTP. now the code is working fine.

    Thanks everyone.

    The query appears fine.

    Most probably the textBox5.Text need to be trimmed or the connection object need to be reinitialized.

    You can also try using EntityFilters.All and see id that works.

    Please Verify your Service Connection is not null.  Your Query is fine, you  have verify about CRM Connection and The Textbox values.
